As most existing device sharing technologies are only abstract operations sharable,such as read and write,virtual desktop users can’t share the device-specific characteristics of USB devices attached to cloud *** this paper,we propose USB device redirection as a peripheral bus extension over an Internet Protocol (ip) *** terminal extends the local peripheral bus to a virtual desktop (VD).The main component of this extension is a virtual peripheral bus driver,which resides in the lowest layer in an operating *** experiments show that this approach enables virtual desktop applications to access diverse features of all USB devices and has sufficient I/O performance.

Active Queue Management (AQM) is an active research area in the Internet community. Random Early Detection (RED) is a typical AQM algorithm, but it is known that it is difficult to configure its parameters and its average queue length is closely related to the load level. This paper proposes an effective fuzzy congestion control algorithm based on fuzzy logic which uses the pre- dominance of fuzzy logic to deal with uncertain events. The main advantage of this new congestion control algorithm is that it discards the packet dropping mechanism of RED, and calculates packet loss according to a preconfigured fuzzy logic by using the queue length and the buffer usage ratio. Theo- retical analysis and network Simulator (NS) simulation results show that the proposed algorithm achieves more throughput and more stable queue length than traditional schemes. It really improves a router's ability in network congestion control in ip network.

HTTP-flooding attack is a much stealthier distributed denial of service(DDoS) attack, challenging the survivability of the web services seriously. Observing the web access behavior, we find that the surfing preference of normal users is much more consistent with the webpage popularity than that of malicious *** on this observation, this paper proposes a novel detection scheme for HTTP-flooding(HTTP-SoLDiER).Specifically, HTTP-SoLDiER first quantifies the consistency between web users surfing preference and the webpage popularity with large-deviation principle. Then HTTP-SoLDiER distinguishes the malicious users from normal ones according to the large-deviation probability. In practice, the webpage popularity plays a key role in attack detection of HTTP-SoLDiER. Due to the never-ending updating of the webpage content and the disturbance induced by attackers, the webpage popularity often varies over time. Thus, it is critical for HTTP-SoLDiER to dynamically update the webpage popularity. We design a reversible exponentially weighted moving average(EWMA) algorithm to solve the problem. Finally, we evaluate the effectiveness of this scheme in terms of true positive(TP) and false positive(FP) probabilities with NS-3 simulations. The simulation results show that HTTP-SoLDiER can detect all random HTTP-flooding attackers and most of the perfect-knowledge HTTP-flooding attackers at little false positive.
